BMS SDK dereferences NULL_PTR

PhilippH — Mon, 28 Sep 2026 11:42:08 GMT

Hi,

in the Phy 665a driver within BMS SDK, pxReqLowConfig is dereferenced, even if it is NULL_PTR (RequestQueueLow sideband not used for gateway device 0 configuration).

Call stack:

Level,Function,Stack Frame,Source,PC,Return Address,Stack Used 0,"<MemManage Exception>","32 @ 0x2040DF00","exceptions.c:101:10",0x0060E874,"[0x2040DF18]: 0x0066D3E0",248 0,"Prv_Phy_665a_SpiPackMessageBatchInactiveSync","24 @ 0x2040DF20","CDD_Phy_665a_MsghSpi.c:2379:104",0x0066D3DE,"[0x2040DF34]: 0x0066D60A",216 0,"Prv_Phy_665a_SpiPackMessageBatch","24 @ 0x2040DF38","CDD_Phy_665a_MsghSpi.c:2551:18",0x0066D606,"[0x2040DF4C]: 0x0066DA8A",192 0,"Prv_Phy_665a_IO_SendMessageSpi","24 @ 0x2040DF50","CDD_Phy_665a_MsghSpi.c:3231:26",0x0066DA86,"[0x2040DF64]: 0x00666D34",168 0,"Phy_665a_IO_SendMessage","40 @ 0x2040DF68","CDD_Phy_665a.c:2037:30",0x00666D30,"[0x2040DF8C]: 0x0066E7FC",144 0,"Bms_TD_Send","24 @ 0x2040DF90","CDD_Bms_common.c:353:22",0x0066E7F8,"[0x2040DFA4]: 0x005D54E6",104

Hello PhilippH

Could you please provide more details on the part numbers you are using? I’d like to check the drivers, and it would also be helpful if you could share the file.

I will be waiting for your response

Have a great day and best of luck.
